my engine light came on today and has stayed on wot can it be. the car is not driving any different. my01 uk300. i have just had the centre decat and b/box fitted but this was over a week ago. i also have an itg panel filter. any thoughts greatly appreciatede. j

Take it to a dealer and get then to check & reset the ECU. This fixed mine! Expect it to be free of charge at your usual service dealer!

Mine went tits up when I disconneced the battery.

good stuff il do that! did u have exhaust and panel filter too?
